8) Hi! I have a Gaffers and Sattler forced air home furnace that needs a new fan blower motor. Can you answer the following questions please?
1) Do you know how much a replacement fan motor would cost?
2) Can you fax to me the specs on the motor that came with it?

3) Do you sell, or do you know who sells this replacement part?

This a before and after of an HVAC Blower where the home was receiving little air flow. They thought the motor was bad. After testing there was nothing wrong found with the blower motor except it was extremely dirty and in dire need of of cleaning. Good airflow was restored after it was cleaned. No new HVAC parts were necessary for this job.

Answer........

First of all pricing on any HVAC parts is a very tricky business when saying it would cost this much or that much to replace the blower motor unless you are very specific. You can go to three different electric blower motor supply stores and get three different prices. Some blower motors just cost more than others and some businesses don't care about competitive pricing because they know they sell a superior product. Without getting into economics I can't give you specific prices on blower motors unless I have the detailed specifications and the brand name of the blower motor you want to buy. It is not in the scope of this website to sell products but simply provide technical information and offer links or other resources to help you find what you want to find. After that it's all up to you.

Secondly, from my experience as an HVAC Master with many years experience in the field the best thing you can do is to call a professional HVAC service company to repair/replace this blower motor. It may not be a bad motor but another cheaper part that needs replacing. An HVAC Professional will be able to make repairs quickly and efficiently. A good HVAC service company will also give you a one year warranty on parts and labor on any HVAC repair and this should give you peace of mind.

Finally, you will have to find a local dealer of Gaffers and Sattler to get detailed spec sheets on your furnace and blower motor. The average residential blower motors range in H.P. (horsepower is how motors are sized) 1/8th all the way up to 3/4th horsepower. Many are 208/230 or 240 volts but there are some that are 120 volts. Does the blower motor need to turn clockwise or counter clockwise and what is the amperage rating on the existing blower motor? What is the diameter of the motor? How is it mounted? A rule of thumb for electrical parts is to always use an exact replacement and many HVAC technicians do their best to find an exact replacement for the part they need but sometimes this is impossible so they will match up H.P., voltage rating, amperage rating, the direction the blower motor needs to turn, the diameter of the blower motor body and get a simliar blower motor. A professional HVAC technician has probably changed a thousand of these blower motors and knows all the ins and outs of doing this job even if an exact blower motor replacement is not available. Just having the knowledge of being able to find a replacement blower motor is one thing but knowing how to change it out quickly and efficiently is another thing which will take the frustration out of it and give you peace of mind and comfort a little quicker than if you were to do the job yourself.

Now, you have all the information here that you need to find a replacement blower motor. Shopping around for air conditioning and heating parts can be a challenge. It's up to you if you want to do it or not and spend the time finding the HVAC parts. Good luck to you and I hope you do a good job if you do it yourself.
